摘要：
The objective of the study is to investigate the phenomenon of fire suppression of a kerosene lamp by water droplet impinging on the flame. The macro-and micro-photographic was used in this experimental work to obtain quantitative data. The main part of the experimental setup is the CCD camera assembled with micro-or macro-photography. A monodisperse water droplet generator was used to generate a droplet stream. The stream was used to extinguishing the flame. The concerned parameters were flow rate, droplet size and flame size etc. The results show that the suppression of a flame without touching the lamp core could be related to the droplet size, frequency and velocity, which could cool down the flame and interfere in the structure of the flame.
